If this flag is set and the user chooses to create a new file, the dialog box closes, and the function returns the specified name. Otherwise, the dialog box remains open. By default, the dialog box creates a zero-length test file to determine whether a new file can be created in the selected directory.
If you enable a hook procedure, the dialog box notifies your hook procedure when a network sharing violation occurs for the file name specified by the user. In this case, the dialog box returns the name of the link file rather than the name of the file referenced by the link file.
You can customize an Open or Save As dialog box by providing a hook procedure, a custom template, or both. However, the Explorer-style and old-style versions of the dialog boxes differ in their use of custom templates and hook procedures. The default title for both Explorer-style and old-style dialog boxes is either " Open " or " Save As. These registry entries affect only the dialog boxes displayed for the user associated with the registry hive. To hide features of Explorer-style Open and Save As dialog boxes, an administrator can set the values in the following table under this subkey:.
The contents of the Places bar are determined by the contents of the following subkey:. You can customize an Explorer-style Open or Save As dialog box by providing a hook procedure, a custom template, or both. If you provide a hook procedure for an Explorer-style dialog box, the system creates a dialog box that is a child of the default dialog box.
The hook procedure acts as the dialog procedure for the child dialog box. This child dialog box is based on the custom template, or on a default template if none is provided.
For more information, see Explorer-Style Custom Templates. An Explorer-style hook procedure receives a variety of messages while the dialog box is open.
These include the following:. In addition, there is a set of messages that you can send to an Explorer-style dialog box to get information or to control the behavior and appearance of the dialog box.
You can use some of these messages to control the behavior of the dialog box. In response to this message, the hook procedure can use the SetWindowLong function to reject the selected name and force the dialog box to remain open.
The code member in the header of this structure contains one of the following notification messages. To retrieve information about the status of the dialog box or to control the behavior and appearance of the dialog box, the hook procedure can send the following messages to the dialog box. Typically, if you provide additional controls, you must also provide an Explorer-style hook procedure to process messages for the new controls.
To make room for the new controls, the system expands the default dialog box by the width and height of the custom dialog box. By default, all controls from the custom dialog box are positioned below the controls in the default dialog box. However, you can override this default positioning by including a static text control in your custom dialog box template and assigning it the control identifier value of stc This value is defined in the Dlgs.
In this case, the system uses the control as the point of reference for determining where to position the new controls. All new controls above and to the left of the stc32 control are positioned the same amount above and to the left of the controls in the default dialog box.
New controls below and to the right of the stc32 control are positioned below and to the right of the default controls. In general, each new control is positioned so that it has the same position relative to the default controls as it had to the stc32 control.
To make room for these new controls, the system adds space to the left, right, bottom, and top of the default dialog box as needed. The system requires the hook procedure to process all messages intended for the custom dialog box and therefore sends the same window messages to the hook procedure as to any other dialog box procedure.
The hook procedure is responsible for initializing these controls and retrieving values from the controls when the dialog box is closed. The default dialog box procedure handles messages for all the controls in the default dialog box, but the hook procedure receives the notification messages for user actions on these controls as described in Explorer-Style Hook Procedures.
The Windows Software Development Kit SDK provides the default dialog box template for the old-style dialog boxes, but does not include the default template for the Explorer-style dialog boxes. This is because the Explorer-style dialog boxes allow you to add your own controls but do not support modifying the template for the standard controls. However, in some cases, you may need to know the control identifiers used in the default templates. The following table shows the identifiers of the standard controls in the Explorer-style Open and Save As dialog boxes.
The identifiers are constants defined in Dlgs. You can customize an old-style Open or Save As dialog box by providing an OFNHookProcOldStyle hook procedure that receives messages or notifications intended for the default dialog box procedure. You can also provide a custom template to use in place of the default template. However, you must write the code to actually write the files to disk.
Display the Save File dialog box and call a method to save the file selected by the user. This method gives you a Stream object you can write to. The example below uses the DialogResult property to get the name of the file, and the OpenFile method to save the file. The OpenFile method gives you a stream to write the file to. In the example below, there is a Button control with an image assigned to it.
When you click the button, a SaveFileDialog component is instantiated with a filter that allows files of type. If a file of this type is selected in the Save File dialog box, the button's image is saved. To get or set the FileName property, your assembly requires a privilege level granted by the System. FileIOPermission class. If you are running in a partial-trust context, the process might throw an exception due to insufficient privileges.
Now, I do know that i can easily go back to the previous type of dialog box by setting the required option in the CFileDialog constructor. Could you suggest how can I get access to the file type combo box for the newer save as file dialog? The content you requested has been removed.
